Passing data between threads with ARC

Here's a bit of magic sauce I found in stdlib channels' implementation: It appears to me that `wasMoved` is a handy little [proc](https://github.com/nim-lang/Nim/blob/f8890a0804b6d05

What Nim projects are you working on?

I read in one of my old computer books(I have ton of them) that the most important/impressive feature in programming is the ability to work on abstraction through naming things. So in a good language assigning names/human concepts to objects should be of upmost importance. It is amazing reading

handmade hero in nim ( warning: noob)

I tried doing the same thing a few years ago. For the most part, the translation is pretty smooth, but I got stuck when Casey started working on the sound stuff - I think because I couldn't find a good wrapper for direct sound back then. I'm not sure if there is one now. Can you describe what i

read over for a better explanation of {.dirty.} {.gensym.} and {.inject.} {.dirty.} is probably the best solution for your case, otherwise you have to annotate everything with {.inject.} template defineStrOprs

Maybe it should have more examples on the documentation.

Docs: Remove gensym from arguments for procs defined in templates?

Thanks for the link. I looked at the pragmas mentioned in response to your comment and am still a bit lost. I was able to declare the template as dirty (which I think is safe) and that worked but doesn't feel robust.

> This should help explain the difference. it doesn't; that's for params, not return type. I've discussed this previously here: [template/macro should return `void` instead of `typed` (synonym and much clearer) - Nim forum](https://forum.nim-lang.org/t/4037) looks like the spec is still unclea

Docs: Remove gensym from arguments for procs defined in templates?

I'm working on a little library with a bunch of distinct string types. Using the advice in the manual, I made a template to define the string operations I need: template defineStrOprs(typ: typedesc) = proc `$`*(x: typ): string {.borrow.} proc `&`*(x, y: typ): typ = typ($

Can you add hacktoberfest topic to more nim-lang repos like fusion, nimble, etc?

Originally you could do a type converions as it was a `distinct` type. This was changed and I think we simply need an accessor.

Are (mutually) recursive generic types possible?

The problem with inheritance is that my base algorithm (operating on `BaseNode`/`BaseEdge`) should be able to create instances of them without knowing about the exact descendants. For now I decided just to pass "constructors" (procs which return instances of base objects) to that algorithm. An

What Nim projects are you working on?

Yep, exactly. Most languages _do_ have blocks, but mostly as a syntactic feature of grouping statements or declaring a local scope. In Arturo, pretty much like in Rebol, a block is a group of words/symbols/etc. They will be treated as statements, or data, or some specific DSL, or Swahili for t

What Nim projects are you working on?

I absolutely will. When I first encountered Forth I wondered why so few language does not allow you to assign a block of code to a word/variable. C has these Preprocessor macros and assembly has labels, Smalltalk and Rebol has "blocks". I know Python has exec(), but it is still a very rare featu
